Check Digit Verification of cas no

The CAS Registry Mumber 94627-82-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,6,2 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 94627-82:
(7*9)+(6*4)+(5*6)+(4*2)+(3*7)+(2*8)+(1*2)=164
164 % 10 = 4
So 94627-82-4 is a valid CAS Registry Number.

Reductive Homocoupling of Organohalides Using Nickel(II) Chloride and Samarium Metal

Liu, Yongjun,Xiao, Shuhuan,Qi, Yan,Du, Feng

, p. 673 - 678 (2017)

A homocoupling method for organohalides and organosulfonates promoted by samarium metal and HMPA, and catalyzed by NiCl2 has been developed. Various organohalides (benzyl, aryl, heterocyclic, alkenyl and alkyl halides), α-haloacetophenones, and phenyl organosulfonates were tolerated, and the reaction afforded coupling products with high efficiency. Excellent chemoselectivity was exhibited between halides and other groups, such as ?COOH, ?NO2, halogen, heterocyclic ring, ester, and ketone groups. The stereoselectivity suggested that the reaction mechanism might involve an organosamarium species.
